AC vs. DC solar battery coupling: What you need to know
In an AC-coupled system, DC power flows from solar panels to a solar inverter, transforming it into AC electricity. That AC power can then flow to your home appliances or go to a battery inverter that converts the electricity back to DC for storage. With AC-coupled systems, any electricity stored in the battery system must be inverted
AC vs DC Battery Storage: What''s right for your home?
The biggest difference between them is in the distances they can travel without suffering major power losses. For example, AC can travel long distances without losing much power whereas DC electricity can''t travel so far but is much easier to store. Since AC is much better than DC for long-distance transmission, the power grid uses AC.
